This LA-X head uses the standard "LA" intake manifold and shaft style rocker system. It is drilled for the proper valve cover and gasket and contains both Chrysler LA and Magnum accessory holes on both ends of the head.

A cast iron replacement, the Indy 360 LA-X Head series is designed for both Small Block LA applications (318-360-415cid). With a host of additions and improvements over the factory originals, these heads are an easy way to get 400 to 550 horsepower out of your Mopar-powered street machine. Features of these impressive heads include 179cc intake and 67cc exhaust runners, a 62cc combustion chamber, multi-angle intake and hardened radiused exhaust valve seats, an improved valve guide design and a highly efficient water jacket to prevent engine hot spots. The 360 LA-X Cylinder Heads also come with an extra thick deck surface to enable angle milling for compression.
